Hydroboost Power Brake System
After 10 years Ford saw the need for power brakes on the early Bronco. Power brakes were optional for the 1976 and 77 model years. They picked a vacuum booster to do the grunt work in the system. That's when the stock tire size was 78-15 (small). Today there are a whole lot of us who choose to run large tires (33's, 35's, 37's, 40's etc.) and we want good brakes too!

When we installed our first Hydroboost system, we were literally shocked at how well it worked. You will be too! The WH Hydroboost System consists of all brand new parts. Nothing rebuilt! The firewall adapter plate bolts the system into the stock holes in your firewall. Only a small modification to the firewall hole is needed. We recommend choosing a complete system including new hydraulic hoses, brake lines, and master cylinder, for a convenient and hassle free installation. You can, however, choose just the parts you want, but this system will NOT work with the stock Master Cylinder.

Select Your Options.
  • The Hydroboost Master Cylinder will work with any hydroboost brake configuration. You can not use your stock master cylinder with this kit.
  • Our Hydraulic Hose Set includes custom stainless steel braided hoses and fittings for your steering box and pump. The hose kit even comes with the cool billet hose clamps you see in the photo. You can select "No Hoses" if you desire.
  • Our Custom Brake Line Set is custom made to order at WH. These are the hoses from the master cylinder to the proportioning valve. Select Rubber or Stainless or you can select the No Hoses option.
  • NOTE: Your proportioning valve or distribution block must be located in the stock position.

More info.
  • Our system will not clear 5.0 or 5.8 EFI with the air cleaner and throttle body mounted on the driver's side.
    See the "Before and After" pictures in the Firewall Cutout Installation Guide below and note the modified section.

After having done many upgrades to my 72 Sport over the years, including front disc from a donor 79 1/2 ton Ford pickup, my brakes were ok. But in the real world of driving among the not so attentive general public, the brakes were weak. I had considered going with traditional vacuum assist power brakes, but did not like the bulk and have lost confidence in the quality and reliability of our imported parts today. This hydroboost system from Wild Horses' seems to be excellent quality and the installation was not complicated. The only issue I had was that I had to file down the brake actuating rod for the brake switch to work properly, meaning that the brakes lights remained on regardless of any adjustment efforts. Fortunately, my initial driving experience was in my neighborhood and these brakes are IMPRESSIVE. It took a little time to adjust to the pedal sensitivity, but they really work good and the overall appearance is excellent without interfering with access to the engine.

Pretty straight forward install. Purchased the flexible lines and adapters from the master cylinder to the proportioning valve...Super nice quality. This system functions awesome with my 35 inch tires. All it takes is a soft touch to the brake pedal to bring her to a stop. Another major point that I cant get over is how much better the engine compartment looks with the master cylinder coming almost straight off the firewall and how much room is in there. Definately put it on the list for Santa. Wish I could add a picture.

Very nice set up. Heed the warning if running 35 inch or larger tires. I could not get the vacuum system to do the job no matter what I did. This is an easy install and worked perfectly without adjustments. Although they give you a variety of fittings I did need to buy an additional one for my early Saginaw pump.
